Abstract : Quarry dust gives improvement in quality of concrete as well as by saving the natural resources. This work investigate the possibility of replacement of fine aggregate by quarry dust after studying the physical and chemical properties, workability and compressive strength of the quarry dust concrete at different percentages of 0%, 25%, 40%, 55%, 75% and 100% replacement for M35 grade concrete. Mix design has been developed as per IRC 044 – 2017: Mix Design for Concrete Pavement, using Sulphonated naphthalene formaldehyde (SNF) as an admixture at 1%, 1.5% and 2%. Optimum strength and workability test values of concrete for various proportion of replacement of sand by quarry dust will be compared with concrete made up of natural sand after 7days and 28days curing. This paper is focusing to produce the concrete pavement of high quality with economical cost of construction by promoting less environmental impacts. Key Words: Quarry dust, Concrete pavement, Sulphonated Naphthalene Formaldehyde (SNF), Optimum, Compressive strength, workability. I.
INTRODUCTION
India has one of the largest road networks in the world with over 5 millions km. MoRTH has decided to move toward the construction of concrete pavement as the default mode of construction on National Highway. Concrete pavement is capable of withstanding heavy loads, such as heavy vehicles, with less deformation rather than asphalt. Concrete roads are widely preferred after taking into account the factors related to service life, fuel consumption, weather conditions, low maintenance cost, less prone to wear and tear defects like rutting, cracking etc. Concrete pavement promotes environment friendly construction practices in execution of road projects. Different admixture and material replacement method are applied nowadays in order to reduce construction cost. Quarry dust replacement method is also a means of reducing construction cost and sustainability of resources.The disposal of the huge quantity of dust has a serious environmental problem in country which does not have large free dumping area. Fine aggregate is obtained by sand mining along the river sites. It may cause adverse environmental problems and degradation to natural resources. Increase in demand and decrease in natural resource of fine aggregate has resulted in the need to identify new sources. So, we need to identify the feasibility of replacement of sands by quarry dust.
serious environmental problems in country of strongly populated like India. In order to rectify this great issue of disposal and demand recycling techniques are very much necessary. Chemical admixture like sulphonated naphthalene formaldehyde are also using widely as a super plasticizer. It can work in less water cement ratio with better workability and high strength concrete. We can use normally this super plasticizer up to 2% in hot climatic region like India. II.
R. Ilangova et al. [2008] It is reported used of quarry dust as an alternative material of sand in concrete at 40% or 50% replacement has more compressive strength, flexural strength and split tensile strength than made with other percentage. Appukutty P & Murugesan R. [2009]. They showed that cement mortar for brickwork fines obtained from quarry dust has better performance than mortar made up of natural sands. There is cost reduction of about 12.5% in brickwork and 20.80% in stone masonry by replacing the sand. The utilization of quarry dust leads to eco friendly construction and economic construction. Manessha Joel et al. [2010] For rigid pavement construction replacement of 20% of fine aggregates by quarry dust with 28 days curing is recommended for a economical cost of construction
Quarry dust is obtained as a byproduct of crushing of rock and gravel to obtain fine and coarse aggregate. About 17 millions tones of dust is produced every year. The disposal of this huge quantity of dust has
